# Canonical URL Checker

> Detect duplicate URLs that resolve to the same content (slashes, parameters, www, HTTP/HTTPS) and get canonical recommendations.

**Category:** Meta & Indexing

## How it works

The Canonical URL Checker runs directly against a live URL or your own pasted content — no signup, no install. Results come back in seconds as a prioritized, plain-English list rather than a raw score, so you know exactly what to fix first and why it matters. It's a focused, single-purpose check, built to answer this one question quickly rather than replace a full meta & indexing audit.

1. Paste in your URL, text, or data — no signup required.
2. The tool runs its analysis and returns results in seconds.
3. Review the flagged issues, ranked by severity, with a plain-English explanation of each.
4. Fix the highest-priority items first, then re-run to confirm.

**Why it matters:** A page that isn't indexed, or is indexed with the wrong signals, might as well not exist — indexation and meta-directive issues are invisible in a normal site review and only show up when you specifically audit for them.

This is a free, interactive, browser-based tool — no signup required. It runs client-side JavaScript, so this Markdown page describes what it does; [use the live tool](https://iliassami.com/tools/canonical-checker) to actually run it.
